Matt Land commented on AIRFLOW-1500: ------------------------------------ We had a similar need- to patch the environment variables at run time. We achieved it by extending the DockerOperator into a new class in /airflow/plugins, and evaluate the xcom in the pre_execute hook. > Allow dynamic assignment of volumes in DockerOperator > ----------------------------------------------------- > > Key: AIRFLOW-1500 > URL: https://issues.apache.org/jira/browse/AIRFLOW-1500 > Project: Apache Airflow > Issue Type: Improvement > Components: docker > Reporter: Gerald Vasend > Priority: Minor > > Currently the DockerOperator allows dynamic command modification via > literal_eval allowing injection of xcom variables. Would like to do the same > for volumes. I have tried using a function but need task_instance to access > xcom and it is not available outside execution of the operator -- This message was sent by Atlassian JIRA (v6.4.14#64029)
